Hi,
digg is a popular site using AJAX to allow comment folding, and other usability
features.

Viewing digg articles, especially opening a few at once in new tabs locks up
safari (Spinning Wheel of Death) and pushes processor usage to 80% or so for
30-200 seconds (on my single processor powerbook G4).

I attach a sample taken during one of these lock-ups. they always resolve, and
the pages then work fine until a reload event.
